Hello

I have the a tree which I am displaying with the following zul:

<tree id="salesorderTree" rows="0" width="100%" model="@bind(vm.salesorderTreeModel) @template(not empty each.children ? 'product' : 'detail')">
<treecols sizable="true"> 
    <treecol hflex="24" label="Varelinjer"/>
</treecols>
<template name="product" var="productNode" status="spn">
    <treeitem>
        <treerow>
            <treecell label="@load(productNode.data.description)"/>
        </treerow>
    </treeitem>
</template>
<template name="detail" var="detailNode" status="sdn">
    <treeitem>
        <treerow>
            <treecell label="@load(detailNode.data.salesorderDetailId)"/>
        </treerow>
    </treeitem>
</template>

</tree>

This will output a simple tree with this layout:

root
    product 1
       product detail 
       product detail 
    product 2
       product detail

and so forth.

This is fine but the problem is when I remove all product details on a product I get an error:

Property 'salesorderDetailId' not found on type no.tisaksen.zk.tree.SalesorderProduct Property 'quantity' not found on type no.tisaksen.zk.tree.SalesorderProduct

This means it's actually trying to render the "detail" template when the detail is in fact not there anymore.

Anyone know how to solve this? Or maybe can see what I'm doing wrong?
